Additional info:

Notifications are displayed correctly from another client.

I can confirm the issue. It's probably related to the changes happening to the frontend recently.

The gntp platform might have this issue as well since it is referencing the same image file. The webostv platform maybe too.

Edit:
It's working in a fresh virtualenv where HASS has been installed via pip. It's only within my dev-fork where it is not working (because of the separate repo for the frontend).

I can confirm the issue as well.

@skeptizzle
What type of installation do you have? hass.io as well?

[skeptizzle]

@danielperna84 yes, 0.57.2, worked in 0.56 if I remember correctly..

[pephumin]

I also experience the same, notification for Android TV and gntp not working.

[danielperna84]

@pephumin
hass.io or another type of installation?

[knirefel]

Same issue here, using hass.io on RPi3

[danielperna84]

This problem seems to be exlusive to hassio users. But I don't know why it happens and don't have a running installation to test it.

[pephumin]

Sorry for a late reply, I was travelling to another country.

My installation is not hass.io. I actually installed from docker to my Synology NAS.

I'm seeing this with the 0.58.1 homeassistant/home-assistant docker image too. As a workaround, inside the container you can run these:

mkdir -p /usr/src/app/homeassistant/components/frontend/www_static/
ln -s /usr/local/lib/python3.6/site-packages/hass_frontend/icons /usr/src/app/homeassistant/components/frontend/www_static/icons

For me, I set them to run when the container starts to get things working again.

@kiall thanks a lot
